Procedures
Once all of those conditions are met, bring the fuel condition lever to the LOW
IDLE position. Verify the fuel ow is approximately 100 pounds per hour, the
ITT remains below 1090°C (1090°C ITT is time limited to 2 seconds) and the
reaches idle RPM of approximately 52%.
Once the engine speed reaches idle (52%
), release the starter switch to
the OFF position and verify the STARTER ON annunciator is not shown on
the PFD. When the engine is cold or if there is a high load on the generator,
it may be necessary to advance the power lever slightly forward of the idle
detent to maintain a minimum idle RPM of 52%
. To prevent the idle RPM
from dropping below 52%
, the power lever may be advanced to obtain
55%
prior to turning the generator switch ON.
NOTE: Typically, the ITT temperature during start will be substantially
lower than 1090°C (approximately 500°C for HI START and 700°C for LO
START).
NOTE: If the STARTER ON annunciator remains shown on the PFD
after the starter switch has been returned to the OFF position, the starter
contactor may be closed and the generator will not function. Perform an
engine shutdown.
CAUTION: Operating the engine under high OAT and higher ground
elevations may cause the ITT to exceed the idle limitation of 685°C. To
prevent an over-temperature condition during ground operations, it may be
necessary to advance the power lever slightly to cause an increase in
and/or reduce engine accessory loads to maintain the ITT within its limits.
CAUTION: If the ITT rises rapidly towards 1090° or if no ITT rise is
observed within 10 seconds after moving the fuel condition lever to LOW
IDLE, bring the fuel condition lever to CUTOFF and perform the engine
clearing procedure described in this section to prevent a hot start.
